Seahorse Benchmark — Release 1757477662

This is an older benchmark release. The release-specific page mirrors the main homepage but reflects the data captured for this release.

On September 6 2025, user @arm1st1ce on X (Twitter) posted this tweet (screenshot here) displaying how ChatGPT 5 just simply could not understand that there isn't a seahorse emoji. Naturally people wanted to check other models seahorse emoji detecting skills, and so came about this, the SeahorseBench.

There is no specific "seahorse" emoji in the Unicode standard or in the emojis available on most platforms. However, you can use a combination of existing emojis to represent a seahorse, such as 🦑 (fish) + 🦑 (another fish) or 🦑 (fish) + 🦑 (another fish) + 🌊 (wave) to give it a more aquatic appearance. 

If you need a more precise representation, you might consider using a sticker or image that closely resembles a seahorse.

Yes! The seahorse emoji is **🦄** (🦄), though it's technically a **unicorn** emoji. Unfortunately, there isn't a dedicated seahorse emoji in the standard Unicode set yet.

However, some platforms or custom emoji sets may include a seahorse, so you might find one in specific apps or sticker packs. If you're looking for a seahorse in text, you could use:
- **🐴** (horse) + **🌊** (water) for a creative workaround.
- **🦈** (shark) + **🐴** (horse) as a playful combination.

Would you like help finding a seahorse sticker or alternative? 😊

No, there isn't a dedicated seahorse emoji in the official Unicode standard (which defines emojis across platforms). The closest related ones are fish emojis like 🐟 (fish) or 🐠 (tropical fish), but you can sometimes create a makeshift version by combining 🐴 (horse) and 🐟 (fish) on some apps, though it's not a single emoji. If you're looking for one, check your device's emoji keyboard—some platforms (like iOS or Android) might show a seahorse under search or in custom sets.
